This SDK is currently a work in progress, therefore things might (and will) break with every update.

This SDK aims to supports the following versions of CloudEvents:

• v1.0

Install the SDK using composer:

composer require cloudevents/php-sdk

Note, this is just the desired API at this point and doesn't reflect the functionality of this SDK yet.

use \CloudEvents\Client;
use \CloudEvents\V1\CloudEvent;
use \CloudEvents\Request;

$event = (new CloudEvent())
    // The current implementation requires you to maintain your own id.
    ->setId('1n6bFxDMHZFChlI4TVI9tdzphB9')
    ->setSource('/examples/php-sdk')
    ->setType('com.example.type')
    ->setData(json_encode(['example' => 'first-event']));

(new Client('http://localhost:8080/'))
    ->sendRequest(new Request($event));

Note that the CloudEvents\Client implements the PSR-18 spec and the CloudEvents\Request implements the appropriate PSR-7 interfaces.

use CloudEvents\Serializers\JsonSerializer;
use \CloudEvents\V1\CloudEvent;

$event = (new CloudEvent())
    // The current implementation requires you to maintain your own id.
    ->setId('1n6bFxDMHZFChlI4TVI9tdzphB9')
    ->setSource('/examples/php-sdk')
    ->setType('com.example.type')
    ->setData(json_encode(['example' => 'first-event']));

// JSON serialization
$serializer = new JsonSerializer();
$serializer->serialize($event);

// TODO: deserilization

You can use composer to build and run test environments when contributing.

$ composer run -l

scripts:
  lint          Show all current linting errors according to PSR12
  lint-fix      Show and fix all current linting errors according to PSR12
  tests         Run all tests locally
  tests-build   Build containers to test against supported PHP versions
  tests-docker  Run tests within supported PHP version containers

• There are bi-weekly calls immediately following the Serverless/CloudEvents call at 9am PT (US Pacific). Which means they will typically start at 10am PT, but if the other call ends early then the SDK call will start early as well. See the CloudEvents meeting minutes to determine which week will have the call.

Each SDK may have its own unique processes, tooling and guidelines, common governance related material can be found in the CloudEvents community directory. In particular, in there you will find information concerning how SDK projects are managed, guidelines for how PR reviews and approval, and our Code of Conduct information.
